Description

复式子母弹簧床垫和座垫 技术领域
本发明所涉及的是一种供人睡眠使用的弹簧床垫和供人座倚使用的弹簧座垫。 特别是通过使用两种具有不同自由高度和不同弹性模量的螺旋压缩弹簧特定组合， 形成的一种双螺旋结构的新型弹簧床垫和座垫。
背景技术
通常的弹簧床垫， 是在一个床垫中使用同一种规格的， 自由高度和弹性模量都 相同的螺旋压缩弹簧， 将其排列起来， 并将上、 下端拉结； 或将同一种规格的螺旋 压缩弹簧个别装袋， 排列并缝合连接， 然后包覆垫层材料和面料制成。 这样做使得 通常的弹簧宋垫都只有一个受力层来承载人体， 因为在自由状态下相同高度的螺旋 压缩弹簧的上端面都处于同一平面内。 结果是， 或者因为受力层弹性模量太大， 造 成床垫过硬， 不能使受力层应顺人体各部位的凹凸曲面而变化， 使人躺卧其上时， 凸出部位局部受压、 不利于人在睡眠时的血液循环； 也缺乏舒适感。 因而不能让人 获得舒适、 卫生、 有益键康的睡眠； 或者因为受力层弹性模量太小， 造成床垫过 软， 虽然受力层能应顺人体各部位的凹凸曲面而变化， 但会使人躺卧其上时脊柱发 生弯曲， 且不便于翻身或改变卧姿。 这两种情形都不利于人的睡眠卫生和身体健 康。
本发明内容
为克服普通弹簧床垫的上述缺点， 本发明通过在同一床垫中使用两种规格的具 有不同自由高度和不同弹性模量的螺旋压缩簧的特定组合， 并通过几种不同的构造 方法， 来构成一种双螺旋结构的、 具有不在同一高度的两个受力层的新型弹簧床 垫。 这种新型弹簧床垫的第一受力层是一个软着陆面 （由弹性模量小的子弹簧构 成） ， 它能够在人躺卧其上时应顺人体各部位的凹凸曲面而随机变化， 密切贴合人 体曲面的部分， 分散和均勻压力； 第二受力层是一个硬着陆面 （由弹性模量大的母 弹簧构成） ， 它能够承载软着陆面完成与人体曲面贴合后的剩余重量， 同时保持人 体脊柱的平直， 并能让人翻身或改变卧姿时轻松自如. 这样就克服了通常的弹簧床 垫的各种缺点。 本发明的这种结构也可以用来制作座垫， 同样可以收到良好的效 果.
具体地说， 本发明由螺旋压缩弹簧组合而成的复式子母弹簧床垫， 其特征在于 这种弹簧床垫是由两种具有不同自由高度和不同弹性模量的螺旋压缩弹簧， 即子簧 A和母簧 B排列组合而成。
上述本发明的复式子母弹簧床垫， 自由状态下排列并组合起来的子簧 A和母簧 B的上端面分别位于两个相互平行的平面内。 同时， 最好子簧 A的上端面比母簧 B 的上端面高 30-150隱。
上述本发明的复式子母弹簧床垫， 子簧 A与母簧 B的下端固定在一起， 但子簧 A 的上端是独立的， 互不牵连。
上述本发明的复式子母弹簧床垫， 子簧 A与母簧 B的下端也可不连接， 这时子簧 A套在母簧 B中， 且子簧 A两端是独立的， 互不牵连。
按类似的结构也可以制造本发明的复式子母弹簧座垫， 这种弹簧座垫是由两种 具有不同自由高度和不同弹性模量的螺旋压缩弹簧， 即子簧 A和母簧 B排列组合而 成。
上述本发明的复式子母弹簧座垫， 在自由状态下排列并组合起来的子簧 A和母 簧 B的上端面分别位于两个相互平行的平面内。 同时， 最好子簧 A的上端面比母簧 B的上端面高 30- 150圆。
上述本发明的复式子母弹簧座垫， 子簧 A与母簧 B的下端固定在一起， 但子簧 A 的上端是独立的， 互不牵连。
上述本发明的复式子母弹簧座垫， 子簧 A与母簧 B的下端也可不连接， 这时子簧 A套在母簧 B中， 且子簧 A两端是独立的， 互不牵连。
下面结合附图和实施例对本发明的技术给予进一步的说明。
附图概述
图 1A、 B及 C分别为一种形式的子簧 A, 母簧 B及复式子母弹簧 C的结构示意图。 图 2A、 B及 C分别为另一种形式的子簧 A, 母簧 B及复式子母弹簧 C的结构示意图。 图 3为本发明复式子母弹簧床垫的结构示意图。
本发明的实施方式
本发明可以通过下述几种方式来实现。
依照附图 1、 做出两种自由高度和弹性模量不同的螺旋压缩弹簧， 即子簧 A和母 簧 B . 子簧 A和母簧 B的底部是两个可以套合在一起的同心圆环， 且子簧 A底部圆 环的外径等于母簧 B底部圆环的内径. 子簧 A的自由高度要比母簧 B的自由高度大 30 ~ 150ram, 较常用的为 30 - 120瞧. 将子簧 A套合于母簧 B中， 使底端齐平， 中轴 线重合， 然后将两者底部圆环绞合， 形成一个双螺旋结构的复式子母弹簧 c , 如附 图 1所示。 为了避免子簧 A与母簧 B在伸缩时相互摩擦， 子簧 A宜做成哑铃形， 而母 簧 B宜做成直简形， 然后依床垫的平面尺寸按照通常的方式将这种复式子母弹簧 C 排列， 并将母簧 B的上下端以串条拉簧拉线， 连结成一整体， 床垫钝边上沿各以钢 丝框连接加固周边母簧。 这样， 每个子簧 A除底端之外的其余部分都是独立的， 彼 此不相牵连， 也不与母簧 B牵连。 如附图 3所示。
在自由伸展状态下， 排列起来的子簧 A的上端面位于一平面内， 形成第一受力 层； 而母簧 B的上端面侧位于平行的、 且稍低的另一个平面内， 形成第二受力层。
通过包覆垫层、 衬、 面料， 形成的床垫就有了两个作用不同的受力层。 当人体 躺卧其上时， 由于子簧 A的独立性， 其应变即不牵连其它弹簧， 也不受制于其它弹 簧。 从而能够完全自由地， 随机地应顺人体各部分的凹凸的伸缩， 使第一受力层完 全贴合于人的体型， 均匀、 分散压力， 实现软着陆功能。 人体的其余重量则承载于 拉结在一起的母簧 B上端面形成的第二受力层上。 由于第二受力层的整体性和较大 的硬度， 实现人体的硬着陆， 保持人持脊柱的平直， 并使人翻身成改变卧姿能轻松 自如。
也可以先将母簧 B排列并拉结起来， 形成整体。 尔后将子簧 A个别装入小麻布 袋， 然后将装袋后的子簧 A套入母簧 B , 使子簧 A的下端面靠自重与母簧 B的下端 面齐平。 如附图 2所示。 由于子簧 A的自由高度大于母簧 B的自由高度， 这样也会自 然形成两个作用不同的受力层， 分别实现上述的软着陆功能和硬着陆功能。 这样做 的好处是由于子簧 A的上、 下端都未与母簧 B连接， 因此， 只要将床垫翻转， 就能 够在另一面形成具有同样功能的二个受力层. 从而使床垫两面都能够使用.
本发明还可以用下述方式实现：
先将母簧 B以通常的方式， 按床垫平面尺寸排列， 并将上、 下端拉结， 并沿床 垫钝边上、 下沿以钢丝框加固， 形成母簧片。 另将子簧 A按相同尺寸排列， 并将下 端拉结形成整体， 周边下端以钢丝框加固， 其上呈自由状态互不牵连， 形成子簧 片. 然后将子簧片叠放在母簧片上， 在两簧片中间设置一层棕丝等弹性耐磨材料做 隔高层。 同时将子簧片钢丝框与母簧片上相邻的钢丝框绞合。 这样也能获得一种有 两个受力层， 分别实现软着陆和硬着陆功能的新型弹簧床垫的主体受力结构. 这样 做的好处是可以使子簧 A的排列不受母簧 B限制， 可以排列得更密集， 从而使软着 陆面上的受力点更致密， 贴合人体的随机性更好. 上述三种方式都可以通过调整子簧 A和母簧 B的弹性模量， 子簧 A的弹性模量小 于母簧 B的弹性模量， 获得适合不同软、 硬度要求的两个受力层。 一般较适宜的子簧 A的弹性模量为母簧 B弹性模量的 1 / 5 - 4 / 5。 按照上述方式结构造出床垫结构主 体之后， 依通常的作法， 包缝麻布， 垫层材料、 衬布和面料. 在包缝麻布之前， 最 好将床垫周边一圈的子簧上端与床垫钝边上设置的钢线框用细麻绳拉结起来， 以免 包覆时将这一圈子簧拉倾斜。
本发明中子簧和母簧可采用普通的碳素弹簧钢或锰弹簧钢制造， 而从实用角度 看最好采用碳素弹簧钢。 对子簧和母簧的弹性模量可通过改变螺旋压缩弹簧的自由 高度、 制造弹簧钢丝的直径及工作圈数来调整， 一般母簧的自由高度为 70 - 260mm, 子簧的为 100 - 400mm; 母簧的钢丝直径为 2. 0-4. 0mm,子簧的为 1. 5-3. 5鼠
应用本发明制作的床垫， 能让人获得更舒适， 卫生的睡眠， 有利用于人的身体 健康。
通常的座垫， 大多以人造泡沫塑料做软垫层加以包覆形成， 存在着弹性模量不 便于根据需要调整； 透气性不好， 人坐倚久了产生闷热、 出汗等不舒适感； 易于老 化而失去弹性； 同时这种废弃物将造成对人类环境的污染等缺点. 上述方案也适合 制作座垫， 克服这些缺点， 让人获得更舒适的座椅。
工业应用性
实施例：
依照附图 1， 使用 Φ 3. 2mm70#碳素弹簧铜丝绕制自由高度为 150mm工作圈数为 5的 母簧 B , 使用 φ 2. 5國 70#碳素弹簧钢丝绕制自由高度为 200mm, 工作圈数为 7的子簧 A。 母簧 B上、 下端圆环外径 80mm, 螺旋线收缩为外径 72mm的直简形； 子簧 A上端 圆环外径 62mm, 下端圆环外径 70mm， 螺旋线逐渐收缩至中腰〜 40mm。 将子簧 A套合 于母簧 B内， 下端齐平， 以铁卡将两者下端圆环绞合， 做成复式子母弹簧 C . 然后 按照附图 3排列。 沿床垫宽度横向紧密排列 18只， 沿床垫长度纵向排列 18行， 行间 距- 25mm。 每一模行相邻母簧上下端以铁卡绞合并以 Φ 1. 6mm碳素弹簧钢丝绕制的串 条拉簧 4根， 沿两侧上下连接起来， 每一纵行母簧也以串条拉簧上、 连接。 在宋垫 钝边一周上下敷设两根 Φ 3. 5毫米钢丝框， 绞合于沿边母簧的上、 下两端外侧. 再以 细麻绳按 "人" 字纹将床垫周边子簧 A上端圆环与钝边上部钢丝框锁结起来. 然后 用串条拉簧沿钢丝框串好. 这样就做成了床垫的结构主体. 包覆庥布时， 将覆盖床 垫上面部位的麻布沿经纬线 45° 角斜裁， 以利于床垫面的伸缩性。 铺垫棕丝后其它 各层村布也以这种方式裁剪。 面料采用伸缩性好的针织类布料， 下衬一层 10mm厚乳 胶海绵或膨胶棉， 与面料绗缝在一起， 以使表面更平整， 也使床垫使用时让人更感 舒适。
